Many of you have been eagerly waiting for the Ad Review Center to arrive in your accounts, and we're happy to tell you that this feature is now available for all publishers. By enabling you to review all ads placement-targeted to your site, the Ad Review Center gives you more transparency and control, and ensures that ads are relevant to your site's content and users.

We wanted to share a publisher's thoughts about the Ad Review Center, so we chatted with Jennifer McDonald, Account Manager at RealNetworks for sites such as rollingstone.com and film.com. Before using it, Jennifer says that "the concerns Real had... were mainly concerns about running competitive ads on our sites." But she says that by using the Ad Review Center, her team has been able to keep competitive ads from running. As she notes, "We are able to quickly review the ads before they run on our sites and block any ads that are considered competitive to our services."

The Ad Review Center is now available for all publishers utilizing placement targeting. You can get started with this feature by visiting your 'Competitive Ad Filter' page, located under the 'AdSense Setup' tab.

Before getting started, we strongly recommend keeping your review preference set to the default of 'Run ads immediately.' This will let you allow or block ads after they have run. If you choose the other option of 'Hold ads,' the ads will await review for 24 hours before being allowed to run automatically. Using the 'Hold ads' setting will keep ads from participating in the auction while they await review, potentially lowering winning bids and your AdSense earnings. Ads that you have blocked can't compete in the auction either, so we ask that you keep in mind the revenue impact of blocking ads or switching from the 'Run ads immediately' setting.
